Three types of messages (informational/run time, error, and
warning) may occur during the reset, startup, or shutdown
process.
Informational messages indicate which component the self-test is testing at any given time.
Error messages indicate a hardware failure or
operating system error. Class errors are grouped into 14 classes ( 1-CE).
They are hexidecimal messages that appear on the front panel
LED display and access port status line. All other errors are considered
non-class, and can appear on the panel or on the system console itself.
If a class error is encountered (see Table 13-1 “Class Error Descriptions” for the types of
classes), the
self-test halts and error messages are displayed.
Warning messages identify noncritical failures that do not prevent the system from booting or halt the self-test.
Information messages, error codes, and warnings are displayed (in hexadecimal)
on the front panel LEDs, the access port status line during bootup,
and the system console. English language messages can also appear in
addition to or in place of a hexadecimal message at the console.

Interpreting Class Errors |
|
Fifteen classes of codes comprise the informational, error, and
warning messages. The class number is the leftmost hexadecimal value for
the singular display and for the second multiplexed (alternating) display.
Table 13-1 “Class Error Descriptions” lists the class error number, its hexadecimal code, and the
cause of the error. To determine an error's class, check its numeric code
in the table. Then locate the subsection
in this chapter which addresses that class.
Table 13-1 Class Error Descriptions
| Err. | Code | Description |
|---|
| 1 | 11xx | Faulty register file.
|
| 1 | 14xx | Execution unit failure.
|
| 1 | 15xx | Instruction unit failure.
|
| 2 | 26xx | Translation look-aside buffer (TLB) failure.
|
| 2 | 27xx | Cache failure.
|
| 3 | 30xx | Faulty system monitor card.
|
| 4 | 42xx | Faulty assist processor.
|
| 5 | 5sxx | Bus protocol error.
|
| 6 | | Reserved.
|
| 7 | 7sxx | Faulty memory.
|
| 8 | 8sxx | Faulty I/O card.
|
| 9 | 01xx and 9xxx | Console test error.
|
| A | 01xx and Axxx | Boot device error.
|
| B | Bxxx | Operating system software error.
|
| C | | Initialization messages.
|
| CA | CAxx | Power fail.
|
| CB | CBxx | Transfer of control.
|
| CE | CExx | ISL messages and error codes.

Categories of "nonclass" errors appear on the following page.
Interpreting "Nonclass" Errors |
|
Besides class errors, the system console also displays the
following types of errors:
High priority machine check (HPMC) detailed errors (XXF0-XXFF)
SYSGEN messages (I/O, MISC, LOG, SYSFILE)
* Multiprocessor errors
These error messages appear after the class errors in this chapter,
in the same order shown in the list above.
If unlisted errors occur, call your Hewlett-Packard support representative.
